Specification of Letters Patent.

Patented June 25, 1907.

Application filed September 7, 1906 Serial No. 277.429-

To all whom it may concern:

Be it known that I, EDWARD F. KUNATH, a citizen of the United States,residing in Jersey Cit State of ew Jersey, have invented certain new anduseful Improvements in Type-Writfollowing is a specification.

This invention relates to the ribbon mechanisms-of typewriting machines,and particularly to means for bringing into use differ- .stretch aribbon of red ent colors of ribbon at will.

I provide two or more separate ribbons of different colors and movableindependently of one another to cover the These "ribbons are Woundsimultaneously upon the usual ribbon spools; and means are provided forcausing either ribbon to cover and uncover the printing point during thetglpe strokes While the other ribbon remains 1 e.

I illustrate my Well known ing machine, in which the usual spools forthe usual ribbon are mounted upon vertical axes one at each side of theprinting point in fronit of the platen. Behind said ribbon, I or otherspecial color, which is wound up simultaneously upon the spools with theusual ribbon. I provide an individual carrier or vibrator for eachof theribbons, one carrier in'front of the other. Said carriers are shownmovable up and down by means of levers. The latter may be substantiallylike those commonly used in the Underwood machine, and may be mountedside by side, either lever being called into operation at the typestrokes. The lever-operating mechanism includes the usual universal-barframe, which reciprocates at each type stroke. Upon said recip rocatingmember I mount actuators, one for each of said. ribbon-vibratinglevers," said actuators being shiftable to engage either one or theother lever. Means are. provided for detaining the actuators in eithershift position. Means are also provided whereby the actuators may beheld in such aposition that neither lever will be operated, so thatneither ribbon is caused to cover the printing point at the typestrokes, this being a convenience when making stencils.

In order to prevent ink offsetting from one ribbon to the other, theribbonnearest the invention asapplied to the in the county of'Hudsonand" printing point.

Underwood front strike W1it-' the platen, so that ink may not transferfrom the other side thereof to the other ribbon. Each ribbon may beinked only on the-side facing the platen' There may also be insertedbetween the ribbons a flexibleinkproof separate protective strip.

As so far described the partsare'in common useupon said Underwood machine. Said ribbon 6 is threaded through anupstanding carrier 23 loosely pivoted at 24 to "the front end of a nfront of the lever 25, which is pivoted upon a shoulder screw 26, thelatter threaded into a bracket 27 fixed upon the rear side of ahorizontal shift rail 28. Said lever 25' has'an' arm 29 extending upfrom said pivot 26 and pro vided whereby the lever is operated duringthe backward and forward movement of said universal bar frame or table21, in a manner presently to be explained.

In rear of the main ribbon 6, I stretch a supplemental ribbon 31 of redor other speclal color, which extends between said spools, and is woundthereon simultaneously with said ribbon 6. The ribbon 31 is threadedthrough a ribbon carrier 40 mounted directly behind thecarrier 23, andhaving ears 4L1 to embrace a which in said machine is the type-gm fixed.vertical "post. Said-ears 41 it will be understood-also confine thecarrier 23 against lateral* dislacement.
